Cold rolled ribbed steel surface has two or three side faces transverse ribs. In concrete, the cold-rolled ribbed steel bars and concrete surface friction and adhesion increased significantly.

While the surface of the cold-rolled ribbed steel bars and concrete crescent shaped transverse ribs between the mechanical bite force, about half the energy of the total adhesive force.

Anchorage performance has improved significantly, helps to reduce the possibility of cracks in the concrete surface.

Advantage of cold rolling device to make 3 ribbed steel bar

Raw materials' diameter:6-12mm

Final products' diameter:5-11mm

High quality and low consumption

Q:What's the Main features of cold rolling device to make 3 ribbed steel barA:Cold rolled ribbed steel surface has two or three side faces transverse ribs.
